Grapefruit Seed Extract

Did you know that there is a natural product that is legal, inexpensive, readily available, and safe that will kill germs on any surface, from your kitchen counter top to an operating room? On top of that, did you know that it is non-toxic, has no odor, and can be mixed with water and and taken internally to kill parasites and viruses?

People have known of the many uses for grapefruit seed extract for years, but for some unknown reason, its popularity and versatility has never been widely promoted. A small bottle will last for many months, so there is little financial incentive for the major conglomerates to inform you of its virtues.

This brochure will explain how to use grapefruit seed extract safely and effectively for a variety of uses, all while saving you quite a bit of your hard-earned money.

Before we get into specific uses, here is a little bit of general information about grapefruit seed extract (GSE). It is available as a concentrated liquid from several different manufacturers, and it comes in different size bottles at most health food stores. It is manufactured using a bio-technical process that isolates all the natural protective elements from the seeds and pulp of the fruit Citrus Paradisi, which is commonly known as grapefruit. The extract from this common fruit has been shown to be effective against many germs, such as Staphylococcus, Streptococcus, Listeria, E. coli, Klebsiella, Legionella, Salmonella, Shingella, Cholera and Pseudomonas. It is also effective against Candida, “Athlete’s Foot”, Aspergillus and Trichophyton, Herpes Simplex I, Influenza A, measles and other animal viruses. Parasites that also cannot resist its actions are Giardia lamblia, Entamoeba histolytica and Chlamydia. While being extremely effective against these unwanted germs, GSE has an additional benefit of leaving the beneficial bacteria in our intestinal tracts that we need for the proper digestion of our food and to maintain a healthy balance of necessary internal “flora and fauna”. GSE is a powerful compound and it should be treated with respect. Never drink it or place it on your skin for a prolonged period of time at its full strength; ALWAYS dilute it or rinse it off when it is applied directly to the skin. Avoid contact with eyes. If there is skin irritation, aloe vera or vegetable oil can help relieve the symptoms. Keep out of reach of children. The information contained in this brochure is not intended to be a substitute for proper medical care, and is offered in good faith for educational purposes only. People who have known allergies to grapefruit and citrus should proceed with great caution when applying it to their skin or taking it internally.

NOTE: Grapefruit juice can have serious, and sometimes fatal, interactions with many common prescription drugs. A few of these drugs are Seldane, Procardia, Adalat, and Plendil. Check with your doctor or pharmacist if you are taking any prescription medications before ingesting grapefruit in any form, be it in a juice or the fruit. If you are unable to get a satisfactory answer from your health care professional, reference The People’s Guide to Deadly Drug Interactions (St. Martin’s Press) by Drs. Joe and Terry Graedon. These potential interactions cannot be emphasized too strongly; some physicians and pharmacists are unaware of the dangers of mixing grapefruit with certain prescription medications. If your particular health professional isn’t familiar with these interactions, find someone else who is. This issue is too important to not investigate thoroughly if your are taking prescription mediations.



Vegetable/Fruit or Meat/Poultry Disinfectant

Either add 30 or more drops of GSE to a sink full of cold water and briefly soak your food before you prepare it OR make a mixture of 20 or more drops and water in a 32 oz. spray bottle (available at any discount store), and spray liberally. Not only will germs and bacteria be killed, but dirt and pesticides will rinse off more easily. There is a new product on the market called “Fit” which serves the exact same purpose as this homemade mixture, only you are paying quite a bit of money for the water that is mixed in with the GSE. By not buying a bottle of “Fit” and using your own homemade mixture, you will have already saved the money you spent for this brochure.


Toothbrush Disinfectant

Add 5-10 drops of GSE to 5 oz. of water and soak your toothbrush for a minimum of 15 minutes, or leave in the water between uses. Rinse before using, and change the water weekly. You can also soak your tweezers and nail clippers (in a separate solution, of course) to disinfect them before each use.


General Disinfectant

A 32 oz. spray bottle (available at any discount store) filled with distilled water and 50-100 drops of GSE will work wonders as an all-purpose disinfectant. You can spray counter tops, diaper pails, cutting boards (let sit for 30 minutes before using again), operating rooms, cat litter boxes, sinks, toilet seats, inhalers, public phones, shared exercise equipment, bird cages, dog runs, veterinary offices, nursing homes, public baby changing tables, day care centers, restaurant equipment, or any other place where germs are likely to be passed on. People who handle reptiles, especially iguanas, should spray their hands with this solution after touching their animals to prevent the spread of salmonella. The use of this mixture is limited only by your imagination. Germs multiply best where there are moist, warm conditions. Dry air is a very effective sterilizer, but not every surface has the luxury of being able to be thoroughly dried before each use. A small bottle holding the GSE/water solution can be carried around in a purse or diaper bag if the need arises. While you can control to level of cleanliness in your own home, it is unrealistic to expect your high standards to be met by the general public.

Keeping a ziploc plastic sandwich bag filled with several paper towels lightly soaked with this mixture can make for an easy clean-up before and after meals where hand washing facilities aren’t available. Commercial hand wipes usually contain petroleum-based solvents, chemicals that some people cannot tolerate.


Dish Water Sanitizer

Add 15-30 drops of GSE to your dishwater or add 15-30 drops to your automatic dishwasher detergent or final rinse. Be sure to dip your dishrag in this solution, as it is one of the most germ-laden items in your house. If you don’t use GSE in your dishwater, be sure to spray your dishrag with the general purpose spray bottle. Germs thrive on moist surfaces, and you need every bit of ammunition you can get to fight them off.


Carpet Shampooers/Floor Mopping Water

Add 10-15 drops per gallon to the reservoir to protect against Staph, Strep, Aspergillus, Salmonella, and other common bacteria.


Algaecide For Fish Tanks

Using 70-200 ppm will keep that nasty algae from building up in your fish tank.


Swimming Pools and Hot Tubs

Use GSE in lieu of chlorine to combat algae, bacteria and fungi.


Laundry Disinfectant and Sanitizer

Put 4 - 6 drops in the final rinse water to help kill harmful bacteria. Especially useful in health care facilities or nurseries.


Humidifer and Resevoir

Put 3 - 4 drops per gallon in the water reservoir to prevent fungi, viruses and bacteria.


Fungicide For Soil

Spray the surface of the soil with a solution of 1 drop well mixed into 1 quart of water.


Disinfection Agent for Waste Water

GSE can be used in large quantities as a disinfection agent for domestic waste water treatment plants. The chances of a private citizen implementing this product on such a large scale are slim, but it is worthwhile to know the extent to which GSE can be used.



Cysts and Warts

Apply 1 drop directly to the cyst or wart and after it has been absorbed (blot excess with a tissue), cover with a bandage.


Poison Ivy, Poison Oak, Skin Disorders

Mix 1% concentration (1 part GSE to 100 parts water) with other essential oils (such as chamomile or tea tree--ask at your local health food store), apply with a spray bottle and leave on skin, OR apply 2-3 drops to a wetted area (do not use full strength), leave on the skin for a few minutes, then rinse off.


Cuts and Scrapes

Thoroughly wet a cotton ball or soft rag and apply 1 drop of GSE to it. Rub the GSE into the water on the cotton ball with your finger to make sure it is diluted. Gently dab the cut or scrape with the diluted extract and cover with a bandage.


Nail Fungus and Athlete’s Foot

Mix 3 - 4 drops per 8 oz. of warm water. Soak for 10-15 minutes. The treatment may need to be repeated several times a day. The general purpose spray can be misted on the affected area if soaking is not convenient.


Skin Cleanser/Acne Remedy

Mix 1 - 2 drops in soaps, cleansers, or apply directly to wetted skin, massaging in a circular motion for one minute. Rinse thoroughly when through.


Wrinkle Reducer

Believe it or not, GSE can actually help reduce those tiny lines around your eyes and mouth! Being a fruit acid, it will make your skin “puff up” as a reaction to the acidity, thereby making facial lines less noticeable. Why pay $50 a jar at the cosmetic counter when you can achieve the same results for mere pennies? Thoroughly wet a cotton ball, add 1 (and only 1!) drop of GSE to the surface, then carefully wipe it over the areas you wish to enhance. Leave on overnight, and in the morning, you will see a reduction in your facial wrinkles. Remember, the lines haven’t disappeared completely; the skin has been mildly irritated, which makes it “puffy”, thus reducing the appearance of wrinkles. Be sure to keep the solution out of your eyes, as it will burn. Rinse with warm water for 10 minutes if you accidentally get the GSE on your eye. Wearing sunblock, sunglasses and a hat will be far more beneficial in the long run towards preventing wrinkles than trying to cover them up after they have appeared. Never apply GSE directly to unmoistened skin for any reason.


Scalp Treatment (including Dandruff)

Add 5 - 10 drops of GSE to each shampooing. Mix it into the shampoo ahead of time or in your hand before applying, and massage into your scalp. Leave on your head for approximately 2 minutes, then rinse off thoroughly with water. May also be used alone (without shampoo). Do not leave on head for longer than 15 minutes, and always rinse off.





“Traveler’s Diarrhea” can be prevented with GSE using several methods. One way is to add 2 drops in a glass of water at noon and at bedtime (mix thoroughly before drinking). If you are eating out, mix 3 - 4 drops in your beverage if what you are drinking has not been boiled just prior to your consumption of it. If you do come down with a case of “Montezuma’s Revenge”, mix 5 - 15 drops in 5 oz. of juice or water and drink that amount 2 to 3 times daily. Children (ages 3 - 10) should mix 2 - 5 drops in a 6 oz. glass of juice and drink that amount once or twice a day. Do not put the GSE directly in your mouth for any reason. A beneficial supplement to the GSE is acidophilus (the “friendly” bacteria found in yogurt), which can be added to your diet by eating products containing it, or by purchasing capsules from the refrigerated section of your health food store. A prolonged case of diarrhea can strip your intestinal tract of a great deal of the beneficial bacteria needed to digest food; without these natural defenses, your body becomes a host for the undesirable bacteria or parasites,allowing them to multiply unchecked. If the diarrhea persists, contact a physician immediately.


Dental Rinse

To keep your gums healthy and your breath fresh, mix 2 - 3 drops of GSE into a small glass (2 oz. or more) of water. Swish the mixture around vigorously for 10 seconds or longer, then spit. Use this method twice a day. GSE makes a wonderful additive to your Waterpik (or similar brand), especially if you wear braces on your teeth; add 3 - 5 drops to the water reservoir.



Mix 3 drops of GSE in 5 oz. of water. Swish vigorously for 30 seconds twice daily. Do not swallow the mixture.


Ear Infections

Thoroughly mix 1 drop in 6 oz. of distilled water. Apply 1 drop of the solution in each ear. See your doctor if the infection does not resolve quickly.


Strep Throat/Sore Throat

Gargle with a mixture of 2 - 3 drops mixed in 5 oz. of water. Do NOT swallow as you gargle, except for the last mouthful.


Nasal Rinse (Sinuses)

Thoroughly mix 1 drop of GSE in 2 oz. of water. Drop several drops in each nostril, swinging head quickly forward and down, forcing the liquid into the nasal passages. Repeat 2 or 3 times daily. If the infection persists, seek medical treatment.


Chronic Candidiasis (intestinal and systemic)

Thoroughly mix 2 - 3 drops in 5 oz. of water, vegetable, orange or grapefruit juice. Take twice daily. For resistant cases, take as much as 6 - 7 drops mixed in at least 5 oz. of liquid. If the situation does not improve, see your doctor.


Candida Albican Vaginitis

Douche every 12 hours for 3 consecutive days. Use a solution of 2 drops mixed thoroughly in 6 oz. of distilled water. Again, if the problem does not go away within a reasonable period of time, see your physician.


Broad Spectrum Antiviral

By both cleaning surfaces and objects that sick people touch, and by drinking a preventative amount of GSE daily (1 - 2 drops in 5 oz. of water twice a day), the chances of contracting Herpes Simplex 1, Influenza A, measles, viruses, various animal diseases (such as salmonella) and the common cold will be greatly reduced. If you suspect that you may have any of these diseases, by all means contact your physician. While GSE is very effective in fighting against viruses and harmful bacterial, it doesn’t eliminate the “friendly” bacteria that we all need to properly digest our food.


Allergies/Hay Fever/Food Sensitivities

Mix 5 - 10 drops of GSE into 5 oz. of water or juice, 2 - 3 times a day, with or without meals. Do not put GSE directly in your mouth.


Water Disinfectant for Emergencies/Camping

First, filter the water if possible, or at least let the particulates settle to the bottom. Add 10 drops to the cleared water, shake or stir well, and let sit for a few minutes before drinking. It may taste bitter, but it’s better than getting sick.       As you can see, grapefruit seed extract is an extremely versatile product. A two ounce bottle costs approximately $10 at the time of this printing, and will last for many, many months. A few drops will go a long way towards making your body and your home healthier and germ-free. As stated earlier, GSE is a powerful and potent substance and needs to be treated with respect. Used properly, it can save you quite a bit of money and prevent unwanted infections and contaminations.       All information in this brochure is accurate at the time of publication.
